ING MECHANISM FOR ROLLER-DIES.

Specification forming part of Letters Patent No. 114,735, dated May 9,1871.

To all whom it may concern:

Be it known that I, HERVEY Wiyrnns, of Boston, in the county of Suffolkand State of Massachusetts, have invented an Improvement in Machines forRolling Metal; and I do hereby declare that the following, taken inconnection with the drawings which accompany and form part of thisspecification, is a description skilled in the art to practice it.

The invention relates particularly to a means of guiding and holding abar or blank to be rolled in position to be seized by the workinggroovesof a pair of die-rolls, the bar or blank supported upon the guide beingthrust through between the parts of the rolls which are lower than theirworking-surfaces, and these held (resting upon the guide) by theoperator in position for the action of the rolls.

The invention consists in the employment, in combination with a pair ofrolls, of a sliding gage-bar, the opposite ends of which are supportedand run upon guide ways or rails, and in combining with said bar a guideor guides for receiving a projection irom the blank or tongs to positionthe blank laterally with reference to thedie-grooves, suitable stopsbeing arranged so that the guide-baris arrested, when pushed between therolls, to bring the bar into proper position to be struck by a shoulderupon one of the rolls, so that the dies always act upon the blank withreference to the position of the projection upon the tongs relatively tothe surface to be shaped.

The drawings represent a rolling-machine embodying my improvements.

Figures 1 and 2 show perspective elevations of the same. Fig. 3 is asectional elevation.

a to denote the stands or housings, in which are jonrnaled the tworolls 1) 0, having parts of their surfaces lower than theirworking-surfaces and having in their working-surfaces the die-grooves,which impart the desired shape to the bar to be rolled.

d is a gage-bar extending across the machine from stand to stand andparallel to the axes of the rolls, and sliding in stationary grooves orways e c. This gage-bar is con nected by links f to the upper ends ofrockerarms 9, extending from a rocker-shaft, h. The gage is normallyheld in front of the rolls or upon the side where the operator stands bya spring or weight, and it occupies such position with relation to thelower roll that when slid between the blank surfaces of the rolls itwill be struck by the shoulder 'i of the lower roll as the rolls rotateand will be carried toward the operator. Upon this gage-bar, in verticalplane with each diegroove, is a guide or projection, k, for positioningthe bar or blank laterally with respect to the die-groove. The blank,grasped in suitable tongs, is laid upon the gage-bar, with a projectionfrom the blank or a projection, I, from the tongs between the guides 70,said projection being against the gage-bar. Theoperator then pushes theblank and gage between the open rolls until the gage is arrested bysuitable stops on the guideways, and the bar will then be in positionfor the action of the rolls. As the rolls turn, they do not immediatelybite upon the blank, but the shoulder i strikes the gage and moves itback, so that the dies bite upon the blank at a point having definiterelation to the part of the blank grasped by the tongs, thus insuringuniform action of the rolls upon the blanks.

I claim- In combination with shaping die-rolls, a movable gage-bararranged with reference to the rolls and to guide the blank,substantially as described, when such movable gage-bar is provided witha guide or guides for positioning the blank laterally, substantially asdescribed.
